From third Health Physics Society midyear topical symposium; Los Angeles, California, USA (29 Jan 1969). See CONF-690103P1. In a brief field evaluation of a new technique for measuring uranium intake in occupationally exposed individuals, the uranium deposited by inhalation in four subjects in a three-day period was excreted almost entirely within two weeks, 95% by fecal elimination. The rapid, nearly total fecal clearance was consistent with upper respiratory deposition of insoluble dust, the airborne uranium having been U/sub 3/0/sub 8/ with an aerodynamic median diameter of about 10 microns. Reasonable agreement between measurements of intake and excretion tend to validate the intake data which were obtained by the technique of monitoring individual exposures by lapel samples and of periodic me-asurement of fractional respiratory deposition using a special breathing apparatus.
